Outlook

Headline: A brief cold, showery spell of weather for the first half of this week. Less cold after midweek, but changeable and unsettled.Tuesday night: Cold under clear spells, with showers retreating to the coastal fringes. Wintry falls possible in any showers that drift inland, with the main risk of this about Ulster. Northerly winds will fall back light, leading to a fairly widespread frost. Minimum temperatures of -1 to +3 degrees.Wednesday: Still rather chilly, but a bright day with sunny spells and showers. The showers won?t be as heavy as on Tuesday and the risk of hail and thunder will have diminished. Top temperatures of 7 to 10 degrees in light to moderate northerly breezes. Wednesday night: Not quite as cold on Wednesday night owing to increased cloud cover, and some patchy rain, chiefly across northern and eastern parts. Still a few clear spells, though, allowing temperatures to fall to between 2 to 6 degrees, in slack northwest winds, leading to a slight grass frost in places. Thursday: Mainly cloudy on Thursday with patchy light rain or drizzle in places. Top temperatures of 9 to 12 degrees in light to moderate northwesterly breezes. Friday and the weekend: Still a degree of uncertainty with regard to the details and timings for the end of this week. Frontal systems in the Atlantic look to make slow progress eastwards, but they will eventually bring unsettled ? wet and windy - conditions to all parts during the weekend. Early indications suggest Friday could hold dry with just increasing cloud amounts, with the wettest and windiest conditions expected later on Saturday and through Sunday.
